Parts with date code of 0915 or newer will incorporate these changes. NO change in performance, form, fit, or function has been made. Some differences in color or shade of color may be expected in the parts. The level of the epoxy fill in the case will be reduced. Models PM3600 and PM3700 remain RoHS compliant*. No change has been made to the termination material. Models PM3602 and PM3604 Epoxy: Substitution of a different compound of the epoxy base. New compound has greater adhesion and higher moisture resistance. Model PM3700 Epoxy: Substitution of a different compound of the epoxy base. New compound has greater adhesion and higher moisture resistance. Case: New case is diallyl phthalate (DAP) material, which is more robust and has greater resistance to moisture absorption than former case material (polyphenyl sulfide – PPS). A list of affected part numbers is included on page 2 of this PCN. All future orders for Models PM3600 and PM3700 will include the revisions noted herein. Data sheets on the Bourns website are current. No change in the data sheets was required. *RoHS Directive 2002/95/EC Jan. 27, 2003 including Annex.
